911 calls
using relay

T-Mobile IP Relay allows registered users to login using an internet connection with a web browser through T-Mobile.com/iprelay.  The following physical geographic location information is essential to locate the most appropriate PSAP.

• Street address
• City, State, Zip Code
• Area code and Phone number from where the caller is located

The caller should be prepared to provide an alternate means of re-establishing contact if disconnected during the 911 call (e.g., a 10-digit phone number with a TTY or a VRS call back number.)  

Steps to Place a 911 Call via the IP Relay web application

1. Caller must be registered and logged in to t-mobile.com/iprelay
2. Using t-mobile.com/iprelay enter “911” as the number to dial
3. The 911 call will be answered in a priority queue by a Relay Operator to process the emergency call
4. Caller will connect with Relay Operator and the emergency call will be placed to the appropriate PSAP based on location information obtained from IP Relay user's profile
5. If one or both legs of an emergency call are disconnected, the T-Mobile IP Relay Operator will attempt to re-establish contact with the caller

NOTE:  The IP user can change geographic location information and select the preferred location to be used in case of an emergency through t-mobile.com/trsprofile.  International address changes are not allowed by the T-Mobile system.

Important:  Although IP Relay can be used for emergency calling, such emergency calling may not function the same as traditional 911/E911 services. By using IP Relay for emergency calling, you agree that T-Mobile is not responsible for any damages resulting from errors, defects, malfunctions, interruptions or failures in accessing or attempting to access emergency services through IP Relay; whether caused by the negligence of T-Mobile or otherwise. Other restrictions apply.

The T-Mobile  IP Relay mobile app allows registered users to log in using a mobile application through the Google Play Store or Apple App Store.  Due to the mobility IP Relay users have today, the IP Relay caller will need to provide their current physical location. This information is essential to locate the most appropriate PSAP.

• City, State, Zip Code
• Area code and Phone number from where the caller is located

Steps to Place a 911 Call

1. Caller must be registered and logged in to the IP Relay mobile application for Android or Apple devices.
2. Turn on Location Services from the Android or iOS device in order to allow your device to provide location information for 911 emergency services.
3. Using the IP Relay mobile app for Android or iOS, tap the "Red Phone 9-1-1" icon and tap OK to connect with emergency services.  
4. The 911 call will be answered in a priority queue by a Relay Operator to process the emergency call
5.  IP Relay mobile users are connected to PSAP or an Emergency Contact Center (ECC)
   
   1. If the Relay Operator can determine the caller’s location, they will route the call to a PSAP.  The PSAP will receive IP Relay caller’s location to dispatch emergency services.
   2. If the Relay Operator cannot determine a sufficiently precise location, the IP call will be routed to the ECC to determine the most appropriate PSAP.
   3. Relay Operator will relay any customer location information available to the ECC.  The ECC can then route the call to the appropriate PSAP, if possible.
   4. If one or both legs of an emergency call are disconnected.  Relay Operator will attempt to re-establish call

Important: Although the IP Relay Mobile Services can be used for emergency calling, it does not function in the same manner as traditional wireline or wireless 911. You must carefully evaluate your individual circumstances in deciding whether to rely solely upon the IP Relay Mobile Services for 911 calling or to make alternative provisions for access to emergency calling services, such as attempting a voice call to 911 using the voice calling capability of your wireless phone. In many instances, when you dial 911 from your wireless phone it may automatically route to the appropriate Public Safety Answering Point ("PSAP"), which may have automatic access to your ten-digit wireless telephone number, as well as automatic location information. You may also wish to consider calling 911 from a landline telephone or wireless telephone using a TTY/TDD device, for example.
